JOHN R. ELLIOTT, OF CAMDEN, NEW JERSEY.

BOOK-DISPLAY LEAF-TURNER.

Application filed March 13. 1998.

To all whom it mary concern:

Be it known that I, JOHN It. ELLio'rT, a citizen of the United States,residing in the city and county of Camden, State of New Jersey, haveinvented a new and useful Book-Display Leaf-Turner, of which thefollowing is a specification.

The purpose of my invention is to heid books, pamphlets and otheradvertising matter and turn it over automatically.

A. further purpose of my invention is to retain sheets or the leaves ofa book in strained position such is due to bending or gravity andgradually move tin` retaining device away from the sheets or leaves.

A further purpose of my invention is to operate the retaining mechanismfor leaves under tension continuously by motor means, such as clockwork, so as to release the leaves one aty a time.

It further consists of other novel features of construction, all as willbe hereinafter fully set. forth.

Figure l represents a top plan view of a structure embodying myinvention, parts being removed. Fig. 2 represents a broken sideelevation of the structure of Eig. 1. F ig. 3 represents a top plan viewof the form of invention which I have illustrated without the books.Fig. 4. represents the struw ture shown in Fig. l in end elevation,parts being shown in dotted lines. Fig. 5, is an elevation of a portionof the cloehF mechanism shown. Fig. 6 is a broken elevation of a stopmade use of by me. Fig. T is a perspective view of one of theleaf-engaging fingers used in my mechanism. Fig. S represents amodification in broken side elevation. Fig. t) is a detail perspectiveview of the eseapement and stop mechanism.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings: I designates a frame or base of any suitablematerial, upon which I mount a motor Q of any desired form. In thisparticular instance I have selected clock work mechanism having frame 3,main shaft 4 and initial gear 5. I illustrate this conventionally,merely showing a train of gears to which I have applied referencenumerals t, 7, S and il. without attempting to set out the exact trainin detail as any suitable train of eloelc gearing will answer for thisillustration. I have extended the end of the main shaft to sup-Speecation of Letters Patent.

Serial No. 420.812.

port a gear l0 and the shaft ll to support gear l), the gears 10 and 1Qperformingl special. feeding function as hereinafter brought out. lmalte use of any suitable hair spring 13 and eseapenient wheel and arm13 and 18 to slow the Clock work me` elianially to a desired degree andto stop it when desired by engagement of a piu u ith the esoapeinentwheel.

The requirements of the mechanism which I have illustrated do notnecessitate lunch movement of the clock-work and l have. therefore. madeuse of a winding lever Il. directly attaehable at any desired point tothe shaft et, in order that the main spring il may be wound a porlion ofa turn b v movement of the lever lst.

I have illustrated a bell 15 and elapper lll conveniently placed to beoperated by lever 14 in its movement, in order to illustrate that alarmmay be given when the ineeh.- anism reaches any suitable position aswhen it is sntiieientiv run down. to have released the leaves held, ashereinafter stated. or io require attention for any other reason.

I place books 1T and lo in proximity to the base and hold them in anysuitahhl manner as by spring arms I9 and 20 upon extensions 21 and 22.held to the hase b r bolts and 2l, so that the bool; shall he retainedwith the ends nl' the pages parallel to the ends of my base l. The.sheets or the leaves of the book are then fiexed from the body of thebook, presenting a portion as .shown so bent as to rest upon arms '2Tand 28 and to he held against said arms hy means of the spring pressedlingers 2U and Btl, portions of whose surface, as at 31 and 32, areformed of ratchet eharaeter to engage with suitable gearing. In thiscase I cause these ratchet faces to be engaged by gears 10 and l2 sothat the tingers will be fed in the proper direction by movement of theclock mechanism.

The arms 9.9 and il() are downwardly directed at the ends to engage withthe parts 25 and 2G of the book by means of springs 33 and 34, whichpress the opposite en of these ngers upwardly at points beyond t thepivots provided for these fingers b v their engagement with the gearsl() and 1Q. It will thus be seen that the fingers Qt) and 30 can hedrawn to the position shown in Fig. 2 by winding the clock-work ineehantism through movement of lever 1l in a ditl t) i il rection opposite tothat of the arron and l that there will be a constant gradual inovelment ot the lever 14 in the direction of the arrow, during the runningof the clock with a retraction of the fingers in the direction of thearrows as shown and release ot' the l leaves as the lingers areWithdrawn from l contact therewith. This inward retraction i of thelingers results in the release of the l leaves a few, preferably one, ata time, with consequent closing ot' these leaves, presenty ing ditierentsubjects matter to the view. i This continues until the clock-Work runsdown or is stopped as by pin 38.

l recognize that. other motor mechanism than clock-work could be madeuse ot and that the retracting, retaining fingers may be variouslyformed to perform the functions required. I further recognize that theform of the base and support for the book may be conveniently variedwith part of the advantage from my invention.

In the form shown in Fig. 8, I have illustrated the mechanism as appliedto a stili? backed book. The mechanism is the same as that illustratedin my other figures except that vl have passed one cover of the book 35,between the spring 19 and the extension 21, retracting this spring 19 toposition shown if desirable. The back 35 is thus clamped in eti'eetbetween the base and extension, and the cover Sti is held to theextension by any suitable means as by clamp 37. This retention of stillcovers of the book brings the book within the control of my operatingmechanism so as to make it possible to operate the body ot the book insubstantially the saine manner as a book with a flexible cover. It willbe seen that clamp lf) may still be used tor the purpose illustrated inFig. i?. notwithstanding that the still' covers ot' the book are held asin Fig. 8, the cover 351 in that case departing from the positionillustrated and assuming a position at a slightangle to the extension 21when the body oi the book is held as seen in Fig. 2, It will be evidentthat the structure shown may be used vertically, as in the illustrationof Wall paper, maps and similar objects, one end only being made use ofin such case.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is :n4

l. In a device of the character described, a continually n'iovablemotor, retractable fingers moved longitudinally thereof by said motor,and means tor holding the fingers in Contact With the leaves.

In a device ot' the character described, a frame, a clamp retaining abook with its back toward said frame, a motor and a longitudinallymovable linger controlled by said motor and engaging the leaves of thebook.

3. In a device ot the character described, a trame, a motor thereon, aretaining clamp, a finger extending from said motor, a spring forcausing pressure of the linger against the leaves and means forwithdrawing the finger longitudinally from the leaves.

4.. In a device ol the character described, a frame, a clamp upon saidframe, a motor, a finger movable longitudinally by movel ment ot' saidmotor and means for pressing the finger toward the trame.

5. In a device of the character described, a frame, a motor mounted uponsaid frame, controlling` mechanism for said motor, a linger, means forsupporting a book and lncans for retractinp` said finger longitudinallyfrom engaging said book.

G. In a book leaf' turner, a trame, a clamp for the book, a fingerengaging the leaves of the book, and means for continuously andautomatically moving the linger in the direction of its length.

7. In a device. ot the charaegter described, a traine. a clamp in],iroxiinity to said frame. a finger, means for pressing the fingertoward the frame, and means for causing movement of said finger in thedirection of its length.
